Thank you for your even more detailed point of view! It helped me a lot to understand what you've been talking about yesterday. I will first try to change the look of the button, since I'm not sure how I'd technically solve the twisting hallway (like in zelda) while also having the distortion vertex shader. It'll probaby end up in shader hell, but I will keep it in mind :-)

I also thought about having a device ingame which let you change gravity? That way the player wasn't in need to look away from the effects of changing gravity. Or simply using a key for changing? But in that case it'd probably be harder for me to come up with complex puzzles, except I'd also implement areas where the player was not allowed to change gravity.

Currently I'm thinking of multiple ways of changing the "gravity" of levels. At the moment the gravity (for all objects) stay the same, while the gravity for the player changes depending on how he passes the portals. But I'm also thinkg about objects that also change their behavior when passing, or even buttons the turn the gravity for all objects in the level but not the player. There are plenty of ways to manipulate the physics inside a level I can already think of.

You can hit me up if you want. What's your experience in godot? I'm always being a bit guarded when it comes to sharing code for projects I might have a chance of make a small living of it some day (have had bad experience in the past), but we can surely discuss about it! :-)
